Unity in Diversity & Greywater Guidance

This open source article titled "Development of guidance for sustainabile irrigation use of greywater in  gardens and small-scale agriculture in South Africa" is remarkable for many reasons, but most importantly, for the recognition of kitchensink wastewater in the country's water reuse portfolio. Yes, they recognize there are some apparent *hazards* and that the residual oils may be an issue, but the treatment technology is simple - a mulch filter. Sound familiar? Sure, the Greywater Guru Art Ludwig at Oasis Design also discusses the importance of mulch filters, too. Check out this handy decision making chart that the authors developed, along with this great risk management table; elsewhere in the article is a guide on volumetric application. 

From the study, the following recommendations are necessary to facilitate greywater use in South Africa:
  • Enshrining greywater use as a permitted water use in relevant legislation at national level
  • Capacity building at provincial and municipal level
  • Educating potential users at settlement or household level, and involvement of potential users in planning greywater use projects at municipal level
  • Integration of greywater-use provisions in new developments at municipal level
  • Municipal and provincial authorities developing an enabling environment in low-income settlements through:
  1. Building a sense of community
  2. Improving communication between authorities and settlement representatives
  3. Providing infrastructure for water, sanitation, wastewater and solid waste
  4. Providing infrastructure and guidance for greywater use in exchange for some form of incentive scheme.
Some valuable lessons here, especially as Oregon gets their greywater permit machine running in 2012.

  1. Our country has a real fresh water problem, in many areas the water shortage is critical. I would like to share this that will surely help in water conservation as well as our unemployed veterans:


    They will hire vets to install low flush toilets. A Vet can have a well paying job and 9000 gallons of water per year will be saved! They can hire wounded worriors too.
